given response due to increasing crop intensity and usage of high yield varieties and soil and crop are deficient of potassium (Malik et al., ). A field study was conducted to assess the effect of different sulfur (S) fertilizers on rapeseed crop and plant available S (SO 4-S) status of two S-deficient soils. These soils were located in Pothwar, rainfed areas of Pakistan. Three S fertilizers were applied at five different levels (0, 10, 20, 30 and 40 kg S ha-1). The three S fertilizers. Abstract. Widespread nutrient deficiencies have emerged as the major soil-related constraints, with sulfur (S) being one among them, for sustaining rice–wheat productivity in many parts of the north-western Indo-Gangetic Plain (IGP) and the Western Himalayan region (WHR). Therefore, soils from different agricultural development blocks (ADBs) Cited by: 3. efficiency of gypsum as a source of sulfur to oilseed crops on soils deficient in sulfur and concluded that it was as effective as other sources, such as ammonium sulfate and sodium sulfate. Khosla and Abrol () suggested that gypsum having size finer .

Sulfur is emerging as a major plant nutrient for crops grown in the Indo-Gangetic Plains spread over 13 million hectares in Pakistan, India, Nepal, and Bangladesh. The extent of sulfur deficiency in soils in the region is continuously increasing with the adoption. A soil having % C is considered to be sufficient in organic matter, but Pakistan soils are having less than that. In a survey conducted by Farooq-e-Azam it is reported that the range of soil carbon in Pakistan soils is to % in different soil series. Most of them have less than 1%. Accurate definition of the sulfur (S) soil test–crop grain yield increase (response) relationship is required before soil S test measurements can be used to if there are likely to be responses Cited by: Effect of Zinc, Boron, Sulphur and Magnesium on the Growth and Yield of Potato.

The soil varied in pedological origin and were divided into three groups based on their total nitrogen:total sulphur (N:S) ratios. Herbage yield of alfalfa (full bud) and rape (flowering) were highly correlated (P Cited by: Based on reconnaissance soil survey data and information covering about 62 m ha, the soil resources of Pakistan are described in terms of land capability classes and subclasses, followed by a discussion of soil-related problems affecting agriculture. The problems relating to soil physics have been high-lighted. Of special significance is surface crusting on m ha, for which special tillage Cited by: Inorganic soil S and SO 4 2− adsorptoin. Inorganic S is generally much less abundant in most of the agricultural soils than is organically-bound S (Bohn et al., ). Sulphate is the most common form of inorganic S and can be divided into SO 4 2− in soil solution, adsorbed SO 4 2− and mineral sulphur Cited by: Chapter 8 – Nutrient management guidelines for some major field crops sulphate performs better than others on S-deficient soils. To unirrigated wheat depending solely on stored soil moisture and seasonal rainfall, N rates varying from 40 to kg N/ha can be applied depending on stored soil moisture as described above (Figure 36).File Size: KB.
